Its an Edexcel June 2010 paper.
So I have worked out the routes that should be travelled twice
They are EG + CB (CA + AB).
So when I actually draw the extra path in the graph to find a route, do I draw two lines EG and CB directly or do I draw three lines? EG AB CA?
D1 route inspection question - find a route starting and finishing at A? Watch

You draw EG AB and CA. Then you can find a route, otherwise if you just draw CB then you won't have enough nodes listed. Hope that helped

The thing with route inspection when you're trying to find which arc to go through twice, you always do it so that you repeat a arc.
You would draw EG, CA and AB.
you wouldn't do CB if there wasn't an arc connecting the two nodes, or if there aren't any other alternatives that give a smaller length.
Hence the reason why it tells you to minimize the route as much as possible.
